 whose means will be ample enough to enable them to monopolize 

 the largest share. 



' The species enumerated, and the brook trout, (5. stellatus), are 

 the only fishes fi-equenting the fresh waters of Alaska, that have 

 much interest for mankind in general. 



Passing now to the more immediate and better known regions 

 of the great Northwest, in which we include all that country which 

 lies beyond the Upper Mississippi River, and especially that be- 

 yond the eastern foot hills of the Rocky Mountains, we shall 

 attempt to particularize all the recognized varieties except the sea 

 salmon, which we prefer to class among the fishes of the Pacific 

 Coast, under which head they will be found. The following list is 

 given by D. S. Jordan and Herbert E, Copeland in their paper en- 

 titled " Check List of the Fishes of the Fresh Waters of North 

 America," {Bulletin of the Buffalo Academy of Natural Sciences, 

 p. 144, December, 1876.)
